    摘要: A vehicle steering apparatus includes a drive unit for changing a steering angle of a steered wheel. A calculation unit calculates a control target amount of the steering angle based on a vehicle model. A control unit controls the drive unit to change the steering angle based on the control target amount. A determination unit determines whether the absolute value of at least one of yaw rate of the vehicle and lateral acceleration of the vehicle is greater than or equal to a predetermined value when velocity of the vehicle is less than or equal to a predetermined velocity. The control unit refrains from executing the control based on the control target amount when the absolute value is not greater than or equal to the predetermined value.

    摘要: The present invention compensates for a variability in steering angle of a wheel when a vehicle has been stopped, thereby performing an accurate automatic steering. To guide a vehicle stopped at a start position via a reversing position to a target position, the vehicle is automatically steered based on data for a steering angle of a wheel relative to a previously stored traveling distance of the vehicle. The steering angle at the time when the vehicle is stopped at the start position (1) is varied every time and is not necessarily equal to an initial standard steering angle intended to start an automatic steering control. Therefore, at the start position, the automatic steering control of the vehicle is started after equalizing the steering angle of the wheel to the initial standard steering angle, so that the vehicle can be correctly guided to the target position.

    摘要: When an automatic parking control operation is carried out, while allowing a vehicle to creep at a low speed, a net braking force applied to the vehicle is appropriately estimated. That is, not only a braking force generated by operation of a brake pedal but also a braking force generated due to an inclination or unevenness of a road surface or the like are taken into consideration. When the vehicle speed is, for example, in a range of 3 km/hr to 10 km/hr, it is determined that a suitable braking force has been generated for carrying out the automatic parking control operation. To bring the vehicle speed into the predetermined range, it is necessary a) to generate a braking force by operation of the brake pedal on a flat road, b) to generate a negative braking force (a driving force) by operation of an accelerator pedal on a steep ascending slope and c) to generate a larger braking force by operation of the brake pedal on a descending slope.

    摘要: An automatic steering control performs an automatic parking control which automatically steers steerable wheels of a vehicle, without requiring a driver to perform steering wheel operation, such that the actual steering angle of the steerable wheels follows a changing target steering angle, whereby the vehicle is moved to a target parking state. When the actual steering angle fails to follow the target steering angle because of insufficiency of the steering drive force of a steering actuator, a braking force difference imparting control is performed so as to apply a predetermined braking force on the steerable wheel located inside a target vehicle locus. As a result, a steering moment is generated in the steerable wheels. This steering moment serves as a force for compensating for the insufficiency of the steering drive force of the steering actuator. As a result, the actual steering angle accurately follows the target steering angle.

    摘要: An electronically controlled power steering apparatus for controlling the steering assist amount of a steering mechanism of a vehicle is controlled in accordance with a fatigue condition of a driver of the vehicle. The apparatus includes means for setting an aimed assist amount, and means for detecting a degree of fatigue of a steering operator. The aimed assist amount setting means receives, as an input thereto, a value calculated by the fatigue detecting means and sets the aimed assist amount in accordance with a fuzzy rule so that the steering assist amount may increase as the degree of fatigue steering operator increases.

    摘要: An assisting power controller for a vehicle power steering device is provided with a microcomputer, which stores in a random access memory a plurality of the latest steering angle data each detected from a steering angle detector each time the vehicle runs a predetermined distance. The microprocessor processes the plurality of steering angle data to calculate a first driving index representing the road condition and then, to decide a first electric current meeting the road condition. The microprocessor also stores in the memory a plurality of the latest vehicle speed data each detected from a speed sensor each time the vehicle runs the predetermined distance. The microprocessor processes the plurality of vehicle speed data to calculate a second driving index representing the state of maneuver by the driver of the vehicle and then, to decide a second electric current meeting the state of maneuvering. The microprocessor thereafter makes an addition of the first and second electric currents and applies the added electric current to an electromagnetic flow control valve which controls the bypass communication of pressurized fluid between opposite chambers of a power cylinder, to control the assisting power generated by the power cylinder based on the road condition and the state of maneuvering by the driver of the vehicle.
